Here is a list, originally compiled by Myszkewicz, with the ECU pinouts for the 04-05 Ralliarts. The list is not yet complete, but it's mostly there, and will be added to at a later time. If there is something specific that you need, or you feel that something is incorrect, please send a PM to Otter.
